Production Lines
What is a production line in RunMark?
A line represents a physical extrusion line, processing line, or machine on your production floor. If it can run different products and you track its schedule separately, it's a line in RunMark.
Line capabilities
Capabilities define which SKUs a line can produce. When you schedule an order, RunMark shows only the lines where the order's SKU appears in the capability list. If a line doesn't have the capability, it won't appear — no guesswork about which machine can run what.
This is the core constraint. Add every SKU a line can physically run to its capability list, even if you rarely run it there.
Speed matrix
The speed matrix is a table of throughput rates — how fast this line produces each capable SKU. Units match the SKU's unit (ft/hr, m/hr, units/hr, kg/hr).
RunMark uses this to calculate estimated run time automatically:
Run time (hours) = Quantity ÷ Speed
Example: a 5,000 ft order for a SKU with a speed of 750 ft/hr:
5,000 ÷ 750 = 6.67 hours
If speed is left at 0, run time calculation won't work correctly. Set at least an estimate.
Changeover times
The changeover matrix defines how many minutes are required to switch from one SKU to another on this line — die changes, purging, cleaning, etc. RunMark accounts for these when placing schedule blocks back-to-back.
If you don't know exact changeover times, start with estimates. You can refine them over time as you observe actual changeover durations. Rough values are better than no values.
Active vs inactive lines
Inactive lines don't appear in the schedule modal or Gantt chart. Use the inactive status for lines that are down for maintenance, decommissioned, or temporarily not scheduling.
Adding and editing lines
Go to Lines in the sidebar and click Add line. Enter the line name, then use the capabilities, speed matrix, and changeover sections to configure what it can run and how fast. You can add capabilities and speeds incrementally — you don't need to fill in every SKU at once.
